Description

  The present invention relates to an image reading apparatus, and more particularly to a technique for continuously reading a large number of documents.

  In general image reading apparatuses (for example, a scanner, a copier, and a multifunction machine), a user can arbitrarily change scan settings (reading settings) in accordance with a document to be scanned. For example, if “monochrome save” is set instead of “color save”, the data amount of the read image can be reduced, and if “resolution” is lowered, the original can be read at high speed. If the “original orientation automatic discrimination” function is enabled, the orientation of the original can be automatically discriminated and the read image can be rotated as necessary. The technique for determining the orientation of the document is described in, for example, Patent Document 1 below.

Japanese Patent Laid-Open No. 06-243287

  The time required for operation of the image reading apparatus is preferably short. In particular, when one image reading apparatus is shared by a plurality of users, the operation time of each user should be as short as possible.

  However, when a large number of originals are continuously read by the image forming apparatus, if a plurality of originals having different processing desired by the user are mixed, a long time is required for the operation. For example, if a document that you want to scan with `` Save in monochrome '' and a document that you want to scan with `` Save in color '' are mixed, the user will need to change the scan settings each time as necessary, and the operation will be complicated. , Operation time also becomes longer.

  If the technique described in Patent Document 1 is used, the read data can be processed so that the directions of the originals are aligned, but different processes desired by the user cannot be executed for each original. .

  The present invention has been made in view of the above circumstances, and when a large number of originals are continuously read, different processing desired by the user can be performed on each of the originals without complicated operations. The purpose is to do so.

  An image reading apparatus according to an aspect of the present invention includes a document reading unit that reads an image of a document, a setting reception unit that receives a basic setting of processing content for the document from a user, and a control unit that controls the operation of the document reading unit. A document orientation detection unit that detects the orientation of the document, and a determination unit that determines whether or not the orientation of the document detected by the document orientation detection unit matches a predetermined reference orientation. When the determination unit determines that the orientation of the document matches the reference orientation, the unit performs a first process on the document based on the basic setting, while the determination unit determines the orientation of the document. Is determined not to coincide with the reference orientation, a second predetermined process different from the first process is executed. Further, the first process is performed when the original is read by the original reading unit. Where And both processes after reading the document by the document reading unit or either.

  According to the present invention, when it is determined that the orientation of the document matches the predetermined reference orientation, the first process is performed on the document based on the basic settings, and the orientation of the document matches the reference orientation. If it is determined not to be performed, a predetermined second process different from the first process is executed. For example, if the reference orientation is a portrait orientation, a user who wants to perform processing different from the basic setting is rotated 90 degrees, placed in a landscape orientation, and read by the document reading unit. A document placed in a landscape orientation can execute a second process different from the first process performed on another document.

  Therefore, when a large number of originals are continuously read, the user's simple process of changing the direction of the original is performed without changing the operation, and different processing desired by the user is executed for each original. be able to. This improves the convenience of the user when setting the process for each document.

  The document feeding unit 6 feeds the document placed on the document tray to the document reading unit 5. The document reading unit 5 uses the light irradiating unit to irradiate the document fed from the document feeding unit 6 or the document placed on the document table (platen glass) and receive the reflected light. To read the image from the document. Image data obtained by reading by the document reading unit 5 is stored in the image memory 32 or the like.

  The image forming unit 12 forms a toner image of an image to be printed on a sheet (recording medium). The image memory 32 is an area for temporarily storing image data of a document obtained by reading by the document reading unit 5 and temporarily storing data to be printed by the image forming unit 12. .

  The HDD 92 is a large-capacity storage device that stores image data and the like read by the document reading unit 5. The fixing unit 13 fixes the toner image on the paper to the paper by thermocompression bonding. The paper supply unit 14 includes a paper supply cassette (not shown), and picks up and conveys the paper stored in the paper supply cassette.

  The operation unit 47 receives instructions such as an image forming operation execution instruction and a document reading operation execution instruction from the operator regarding various operations and processes that can be executed by the image forming apparatus 1. The operation unit 47 includes a display unit 473 that displays operation guidance to the operator. The display unit 473 is a touch panel, and the operator can operate the image forming apparatus 1 by touching buttons and keys displayed on the screen.

  The network interface unit 91 transmits / receives various data to / from an external device 20 such as an electronic device or server in the local area or on the Internet.

  The size sensor 21 is arranged on a document tray and a document table on which documents are placed, and detects the size of the document. For example, the size sensor 21 is provided in a document width alignment guide member constituting the document tray, detects a separation distance (that is, document width) of the guide member, is provided in the longitudinal direction of the document tray, and determines the document length. Detect. The size sensor 21 is provided around the document table and detects the size of the document placed on the document table.

  The control unit 10 includes a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and a dedicated hardware circuit. The processor is, for example, a central processing unit (CPU), an application specific integrated circuit (ASIC), or a micro processing unit (MPU). The control unit 10 includes a control unit 100, an operation reception unit 101, a document orientation detection unit 103, and a determination unit 104.

  The control unit 10 functions as the control unit 100, the operation reception unit 101, the document orientation detection unit 103, and the determination unit 104 by the operation of the processor according to the control program stored in the HDD 92. However, the control unit 100 and the like can be configured by a hardware circuit regardless of the operation of the control unit 10 according to the control program. The same applies to each embodiment unless otherwise specified.

  The control unit 100 governs overall operation control of the image forming apparatus 1. The control unit 100 includes a document feeding unit 6, a document reading unit 5, an image forming unit 12, an image memory 32, an HDD 92, a fixing unit 13, a sheet feeding unit 14, an operation unit 47, a network interface unit 91, and a size sensor 21. Connected to perform drive control of these units. For example, the control unit 100 controls the operation of the document reading unit 5 to cause the document reading unit 5 to read the document fed from the document feeding unit 6 or the document placed on the document table.

  The operation receiving unit 101 receives an operation input from the user via the operation unit 47. The operation reception unit 101 includes a setting reception unit 102.

  The setting receiving unit 102 receives a basic setting and a special setting of processing contents for a document in advance from a user. For example, the setting receiving unit 102 displays the operation screen D1 as illustrated in FIG. 2A on the display unit 473, thereby enabling the basic setting of the scan to be received from the user. In addition, the setting receiving unit 102 receives a special scan setting from the user by causing the display unit 473 to display an operation screen D2 as illustrated in FIG.

  The basic setting is a setting used for a document placed in a predetermined reference orientation (for example, a portrait orientation), while the special setting is a document placed in a orientation different from the reference orientation. This setting is used for.

  The operation screens D1 and D2 have three types of radio buttons that can select only one of them. The radio buttons RA1 to RA4 accept file format settings from the user, and “PDF”, “JPEG”, “TIFF”, and “XPS” are respectively written next to the radio buttons RA1 to RA4. For example, when an operation on the radio button RA1 is accepted via the touch panel on the operation screen D1, the content that the file format is “PDF” is stored as a basic setting. Further, for example, when receiving an operation for the radio button RA2 on the operation screen D2, the setting receiving unit 102 stores the content that the file format is “JPEG” as a special setting. That is, the user can arbitrarily set one of the processes after the original reading by the original reading unit 5.

  The radio buttons RB1 to RB3 are images for accepting a reading resolution setting from the user. Next to the radio buttons RB1 to RB3, “high (600 dpi)”, “medium (400 dpi)”, and “low (200 dpi)” are written, respectively. For example, when accepting an operation on the radio button RB3 on the operation screen D1, the setting reception unit 102 stores the content that the reading resolution is “low (200 dpi)” as a basic setting, and on the operation screen D2, When an operation for the radio button RB1 is accepted via the touch panel, the content that the reading resolution is “high (600 dpi)” is stored as a special setting. That is, the user can arbitrarily set one of the processes at the time of document reading by the document reading unit 5.

  The radio buttons RC1 and RC2 are images for receiving a data storage method setting from the user using the touch panel. Next to the radio button RC1, “monochrome save” is written, and next to the radio button RC2, “color save” is written. For example, when the operation of the radio button RC1 is received on the operation screen D1, the setting reception unit 102 stores the content “monochrome save” as the basic setting. In addition, for example, when the operation of the radio button RC2 is received on the operation screen D2, the setting reception unit 102 stores the content “save color” as a special setting. That is, the user can arbitrarily set one of the processes after the original reading by the original reading unit 5.

  The document orientation detection unit 103 detects the orientation of the document by determining whether the document is portrait or landscape based on information obtained from the size sensor 21.

  The determination unit 104 determines whether or not the document orientation detected by the document orientation detection unit 103 matches the reference orientation.

  Next, an example of processing operations performed by the control unit 10 of the image forming apparatus 1 including the image reading apparatus according to the first embodiment will be described based on the flowchart shown in FIG. For example, this processing operation is performed when the operation reception unit 101 receives a document scan start request from the user. Here, a case where a large number of documents are continuously placed on the document table (that is, a case where a scan start request is made by the user every time the document is replaced) will be described.

  First, when the operation reception unit 101 receives a document scan start request from the user, the document orientation detection unit 103 detects the orientation of the document (S1), and the determination unit 104 is detected by the document orientation detection unit 103. The orientation of the original (that is, the orientation of the first original to be read by the original reading section 5) is set to the reference orientation (S2).

  Thereafter, the control unit 100 controls the operation of the document reading unit 5 and the like in accordance with the basic setting received in advance by the setting receiving unit 102 from the user, thereby executing the first process based on the basic setting (S3). ). For example, as shown in FIG. 2A, as a basic setting, the file format is set to “PDF”, the reading resolution is set to “low (200 dpi)”, and the saving method is set to “monochrome saving”. When the setting reception unit 102 stores the image data, the control unit 100 causes the original reading unit 5 to read the original as a monochrome image at a reading resolution of 200 dpi, and the image data obtained by reading by the original reading unit 5. Is converted to a PDF file. Then, the control unit 100 transmits the data converted into the PDF file to the user-specified external device 20 (for example, a personal computer) received in advance by the operation receiving unit 101 via the network interface unit 91.

  Subsequently, the control unit 100 determines whether the operation receiving unit 101 has received a document scan start request from the user (S4). That is, the user inputs a document scan start request to the operation unit 47 for each document read, and the control unit 100 receives the scan start request from the operation reception unit 101 via the operation unit 47. Assume that the reading unit 5 reads a document one by one.

  In the control unit 100, the operation receiving unit 101 receives a document scan start request from the user (that is, a new document is placed on the document table by the user, and a scan start request for the new document is made). Is determined (YES in S4), the document orientation detection unit 103 detects the orientation of the document (S5), and the determination unit 104 determines that the orientation of the document detected by the document orientation detection unit 103 is the reference orientation. It is determined whether or not they match (S6).

  When the determination unit 104 determines that the document orientation detected by the document orientation detection unit 103 matches the reference orientation (YES in S6), the control unit 100 determines that the setting reception unit 102 performs the same as in S3. By controlling the operation of the document reading unit 5 or the like according to the basic settings received in advance from the user, the first processing based on the basic settings is executed (S7), and then the process returns to S4.

  On the other hand, when the determination unit 104 determines that the orientation of the document detected by the document orientation detection unit 103 does not match the reference orientation (NO in S6), the control unit 100 determines that the setting reception unit 102 has received from the user in advance. By controlling the operation of the document reading unit 5 or the like according to the special setting received in step S5, the process based on the special setting is executed (S8), and then the process returns to step S4. Note that this process is an example of the second process in the claims.

  For example, in the example shown in FIG. 2B, as a special setting, in the setting reception unit 102, the file format is set to “JPEG”, the reading resolution is set to “high (600 dpi)”, and the storage method Is set to “save color”, the control unit 100 causes the document reading unit 5 to read the document as a color image at a reading resolution of 600 dpi, and the image data obtained by reading by the document reading unit 5 Is converted to a JPEG file. Then, the control unit 100 transmits the data converted into the JPEG file to the user-specified external device 20 (for example, a personal computer) received in advance by the operation receiving unit 101 via the network interface unit 91.

  In S4, when it is determined that the operation reception unit 101 has not received a document scan start request from the user (NO in S4), the control unit 100 determines whether it is a timing to end the scanning process (S4). S9). For example, when the operation receiving unit 101 receives an instruction to end scanning from the user, or when the operation receiving unit 101 does not receive a user operation for a predetermined time (for example, several minutes), the control unit 100 It is determined that it is time to end the scanning process.

  If the control unit 100 determines that it is time to end the scanning process (YES in S9), if it determines that it is not time to end this processing operation and end the scanning process (NO in S9), the process proceeds to S4. Return to.

  According to the first embodiment, when it is determined that the orientation of the document matches the predetermined reference orientation, the processing based on the basic settings is performed on the document, and the orientation of the document is set to the reference orientation. If it is determined that they do not match, processing based on the special setting is executed. For example, when the reference orientation is a portrait orientation, the user places a document desired to be processed with special settings different from the basic settings by rotating it 90 degrees in a landscape orientation.

  Therefore, when a large number of originals are continuously read, the user's simple process of changing the direction of the original is performed without changing the operation, and different processing desired by the user is executed for each original. be able to. As a result, the convenience of the user is improved, and as a result, congestion of devices (for example, copy machines) that are shared and used by a plurality of users can be reduced.

  Next, an example of a processing operation performed by the control unit 10 of the image forming apparatus 1 including the image reading apparatus according to the second embodiment will be described based on the flowchart shown in FIG. In the second embodiment, the setting receiving unit 102 is configured not only to receive a basic setting of processing contents for a document in advance from a user but also to receive individual settings of processing contents for a document from the user. This is different from the first embodiment. In the flowchart shown in FIG. 4, the processing operations of S1 to S7 and S9 are the same as the flowchart shown in FIG. 3, and thus description thereof is omitted. Only S11 to S13 are described here.

  In S6, when the determination unit 104 determines that the document orientation detected by the document orientation detection unit 103 does not match the reference orientation (NO in S6), the setting reception unit 102, for example, illustrated in FIG. By displaying such an operation screen D3 on the display unit 473 (S11), a process for prompting the user to perform individual scan settings is executed, and the individual settings are made acceptable by the user. Note that this process is an example of the second process in the claims.

  On the operation screen D3, a message M1 is written, "The orientation of the document does not match the reference orientation (the orientation of the first document). Please perform the scan settings used only for this document." In addition, as with the operation screens D1 and D2, three types of radio buttons RA1 to RA4, radio buttons RB1 to RB3, and radio buttons RC1 and RC2 are formed.

  Subsequently, when the control unit 100 determines that the individual setting from the user has been received by the setting receiving unit 102 (YES in S12), the control unit 100 determines whether the document reading unit 5 or the like is in accordance with the individual setting received from the user by the setting receiving unit 102. By controlling the operation, processing based on the individual setting is executed (S13). Thereafter, the process returns to S4.

  According to the second embodiment, when it is determined that the orientation of the document matches a predetermined reference orientation, processing based on the basic settings is performed on the document, and the orientation of the document is set to the reference orientation. If it is determined that they do not match, the user is prompted to make individual settings for the document, and the individual settings are accepted. Then, processing based on the individual setting is executed. For example, when the reference orientation is a portrait orientation, the user may place a document desired to be processed with individual settings different from the basic settings by rotating it 90 degrees in a landscape orientation.

  Accordingly, as in the first embodiment, when a large number of originals are continuously read, the user can perform simple operations such as changing the orientation of the originals without complicated operations. Different processes desired by the user can be executed.

  In the first and second embodiments, the control unit 100 performs processing based on the basic setting based on the determination result of whether or not the document orientation by the determination unit 104 matches the reference orientation. Although processing based on special settings or processing that prompts the user to perform individual settings is performed, as yet another embodiment, for example, the document orientation detection unit 103 is based on information obtained from the size sensor 21. Not only the orientation of the document but also the size of the document may be detected, and the control unit 100 may perform control based on the size of the document.

  For example, when the determination unit 104 determines that the document size matches the reference size (the size of the first document to be read by the document reading unit 5), and the document orientation matches the reference orientation, The control unit 100 performs processing based on the basic setting. If the determination unit 104 determines that the document size matches the reference size but the document orientation does not match the reference orientation, the control unit 100 performs processing based on the special setting, and the determination unit 104 When it determines with other than the above, the control part 100 performs the process which prompts a user for an individual setting.

  In the first and second embodiments, the document orientation detection unit 103 detects the orientation of the document by determining whether the document is portrait or landscape. The method of detecting the direction of the is not limited to this. For example, as will be described in detail later, the document orientation detection unit 103 detects the orientation of the document by determining the arrangement direction (character direction) of the characters described in the document and the direction of the characters. Also good.

  Next, an image reading apparatus according to a third embodiment will be described. FIG. 6 is a functional block diagram schematically illustrating the main internal configuration of the image forming apparatus including the image reading apparatus according to the third embodiment. The document orientation detection unit 103 includes a portrait / landscape discrimination unit 105, a character arrangement direction discrimination unit 106, and a character orientation discrimination unit 107, and can detect the orientation of the document using a plurality of different methods. The reception unit 101 includes a selection reception unit 108, and the third embodiment is different from the first and second embodiments in that respect.

  Based on information obtained from the size sensor 21, the portrait / landscape determination unit 105 determines whether the document is portrait or landscape, and thereby detects the orientation of the document.

  The character arrangement direction discriminating unit 106 detects the arrangement of pixels (black dots) in the horizontal direction and the vertical direction of the document based on the image data obtained by reading by the document reading unit 5, and is a blank where black dots are not arranged. The larger number is discriminated as the line direction (character arrangement direction), thereby detecting the direction of the original.

  The character orientation determination unit 107 performs OCR (Optical Character Recognition) processing on a partial area of the document image based on the image data obtained by reading by the document reading unit 5 to determine the character direction, Thereby, the orientation of the document is detected.

  For example, the selection receiving unit 108 displays an operation screen D4 as illustrated in FIG. 7 on the display unit. As a result, selection of the method used for detecting the orientation of the document can be accepted from the user. The operation screen D4 has radio buttons RD1 to RD3 that can select only one of them. Next to the radio buttons RD1 to RD3, "Detect the orientation of the document from the portrait and landscape orientation", "Detect the orientation of the document from the character arrangement direction", and "Detect the orientation of the document from the orientation of characters", respectively. It is written.

  When the selection receiving unit 108 receives an operation on the radio button RD1, the portrait / landscape determination unit 105 detects the orientation of the document (whether the document is portrait or landscape). When the selection receiving unit 108 receives an operation on the radio button RD2, the character arrangement direction determining unit 106 detects the orientation of the document (character arrangement direction), and the selection receiving unit 108 performs an operation on the radio button RD3. Upon receipt, the character orientation determination unit 107 detects the orientation of the document (character orientation).

  By the way, the portrait / landscape discrimination unit 105 detects the orientation of the document based on the information obtained from the size sensor 21, but the character arrangement direction discrimination unit 106 and the character orientation discrimination unit 107 are obtained by reading by the document reading unit 5. Since the orientation of the document is detected based on the image data, the orientation of the document is detected not after reading the document by the document reading unit 5 but after reading the document by the document reading unit 5.

  Therefore, when the selection receiving unit 108 receives an operation for the radio buttons RD2 and RD3, the setting receiving unit 102 performs special settings and individual settings (for example, reading resolution) regarding processing when the document reading unit 5 reads the document. Setting) is not accepted. For example, in the operation screen D2 shown in FIG. 2B or the operation screen D3 shown in FIG. 5, the area for setting the reading resolution is displayed semi-transparently or grayed out, and the user setting for the reading resolution is set. Do not accept.

  According to the third embodiment, since the user can arbitrarily select the method used for detecting the orientation of the document, it is possible to improve the usability. In order to determine the character arrangement direction and character direction, it is considered that the processing time is longer and the power consumption is larger than the determination of the portrait or landscape orientation of the document, but for example, various sizes of documents are mixed, When there is a document that makes it difficult for the user to determine whether the portrait is portrait or landscape, it is effective to detect the orientation of the document by determining the direction of character arrangement or the direction of characters.

  In the first to third embodiments, a case has been described in which the determination unit 104 sets the orientation of the first document to be read by the document reading unit 5 as a reference orientation. In this embodiment, the reference orientation may be registered in advance by the manufacturer, or the operation reception unit 101 may receive the prior registration by the user.

  Further, the case of single-sided reading of a document placed on a document table (platen glass) has been described as an example, but the same applies to the case of single-sided reading of a document placed on a document tray. With the configuration and processing, the same effects as described above can be obtained.

  Next, double-sided reading of a document placed on the document tray will be described. In the case of duplex scanning, the user does not always want to process the basic settings for both sides of the document, or the user may want to perform special settings (individual settings) for both sides of the document. It is considered that there are cases where the user desires processing with basic settings and the user desires processing with special settings (individual settings) on the other side.

  Therefore, as yet another embodiment, a character arrangement direction discriminating unit 106 capable of registering a plurality of reference directions (for example, a first reference direction and a second reference direction) in advance and discriminating three or more directions. Alternatively, using the character orientation determination unit 107, the document orientation detection unit 103 detects the orientation of the document, and the determination unit 104 determines whether the document orientation detected by the document orientation detection unit 103 matches each reference orientation. Then, the control unit 100 may perform processing based on the determination result by the determination unit 104.

  For example, the back sky is registered as the first reference orientation and the left sky is registered as the second reference orientation, the document orientation detection unit 103 detects the orientation of the document, and the determination unit 104 matches the orientation of the document with the first reference orientation. If it is determined, the control unit 100 performs processing with basic settings for both sides. When the determination unit 104 determines that the orientation of the document matches the second reference orientation, the control unit 100 performs processing with special settings for both sides, and the determination unit 104 determines that the orientation of the document is the first reference orientation. When the controller 100 determines that it does not match the second reference orientation, the control unit 100 performs processing for prompting the user to perform individual settings.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. In the above-described embodiment, a multifunction peripheral is used as an embodiment of the image reading apparatus according to the present invention. However, this is only an example, and for example, a copy function, a facsimile function, a scanner function, and the like are provided. Other image reading apparatuses may be used.

  Moreover, in the said embodiment, the structure and process which were shown by the said embodiment using FIG. 1 thru | or FIG. 7 are only one Embodiment of this invention, and are not the meaning which limits this invention to the said structure and process.
